About

Kaynos is a private video review tool for BJJ coaches, built by one. It's independent and self-funded — no investors, no growth team, no roadmap written by outsiders.

How it started

Every coach I train with has at some point filmed a great roll, pointed at the phone, and said “you have to see this sweep.” Then the footage ends up in a group chat, buried under other messages, and the moment gets lost. I kept running into it and eventually built what I wanted: a place to upload video, drop timestamped notes, and share specific moments with specific students without any of it being public.

Who's behind it

One person. I use Kaynos for my own training, so when something is broken or missing I usually hear about it the same day. Founded in 2026. Based in Safety Harbor, FL 34695.
